See a solution process below:

Explanation:

Step 1: Add #color(red)(11s)# to each side of the equation to isolate the #s# term while keeping the equation balanced:

#color(red)(11s) - 9s = color(red)(11s) - 11s + 8#

#(color(red)(11) - 9)s = 0 + 8#

#2s = 8#

Step 2: Divide each side of the equation by #color(red)(2)# to solve fr #s# while keeping the equation balanced:

#(2s)/color(red)(2) = 8/color(red)(2)#

#(color(red)(cancel(color(black)(2)))s)/cancel(color(red)(2)) = 4#

#s = 4#
